Hi,
You have to update a library : 
<https://issues.apache.org/jira/plugins/servlet/mobile#issue/GUACAMOLE-1540>
Or update guacamole to last stable release.

Warning : the private key is in the email si you have to use another one for 
your production.

Aurelien

Hi,

I’m using: Guacamole version 1.2.0 and this is the first time I’ve tried using 
Guacamole public key authentication.


  1.  I create an SSH connection with:  "hostname", "private-key" and "username”
  2.  Guacamole SSH connection is successful
  3.  But then prompts to enter:    Key passphrase:  ?

But key has no passphrase?

I tested the RSA key connection with  ‘Renci.SshNet’ and connection was 
successful.
